To all whom it may concern:

Be it known that I, MGOLELLAND MYERS, a 'citizen of the United States,residing at Moosic, in the county of Lackawanna and State `ofPennsylvania, have invented certain new and useful Improvements inGlass-Manufacturing Apparatus, of which the following is aspecification.

This invention relates to glass-molding machinery, and particularly to amachine for successively bringing a series of molds into operativeposition with relation to a plunger and in novel means for arresting thetable carrying the molds when said molds have been brought intooperative relation to the said plunger.

Furthermore, an object of the invention is to provide novel means foreifecting the rotary movement of the mold-core, whereby the said core isturned to remove the core Afrom the hollow being .cast in the mold. Ihave described in two companion applications a mold of the characterdesigned for use in connection with this means, and in a secondapplication I have disclosed a mechanical inovement for rotating thecore for eject-A ing the article from the mold. It is to be understoodthat the mold shown in this drawing is to be'the saine in details ofconstruction as the mold described inthe said companion application andthat the mechanical means for providing the rotary core would beutilized in'this machine to forego a similar result. Therefore the moldwill not be described in detail nor will the mechanical movement bedescribed in detail; but reference will be had to the said companionapplications for the understanding of these features.

A further object of the invention is to provide a novel means foradjusting the presser- Ahead in order that its truck may be varied tosuit particular requirements.

Finally, an object of the invention is to produce a glass-mold of thecharacter noted which will prove eflicient and satisfactory in use andprove inexpensive to manufacture.

vcombination of parts to be hereinafter more fully set forth andclaimed.

In describing the invention in detail reference will be had to theaccompanying drawings, forming part of this speciiicatiomwhere- .in likecharacters denote corresponding parts throughout the several views, andin which- Figure 1 is a view in elevation of a glassmolding machineembodying the invention. Fig. 2 is a sectional view on the line 2 2 ofFig. 1, and Fig. 3 is a plan view of the table.

In the drawings, 2 denotes supportingwheels mounted on axles 3, whichaxles are suitably secured `to a body or bed-plate 3L in any well-knownmanner. In the drawings it isillustrated by one of the axles 3, beingprovided with a fifth-wheel 1, through which passes a king-bolt 1a. Theremaining axle is secured to the bed-plate 3a in any preferred manner bythe bolt 1b. Plates 1c are carried by the upper surface of the bed-plateas a support for the pins or bolts 1a 1b.. This construction is no partof the invention and may be changed to suit the various uses ofpractice, the essential feature being a suitablysupported bed-plate.Centrally of the bedplate 3a is a standard 4, on which rests a platform5. mounted a table 6, and in the opposing faces of the platform andtable is a series of annular grooves a, forming raceways for theantifriction-balls b. Secured to the bed-plate 3a is a sleeve 7,provided with a longitudinal slot 7@ Working within the sleeve is aportion of a plunger 9, which passes up through a suitable aperture inthe platform 5 and engages one of the apertures 12 with which the table6 is provided. The portion of the plunger within the sleeve 7 carries atreadle 8, which passes through the slot 7 of the sleeve and'is adaptedto be engaged by the foot of an operator to withdraw the plunger 9 froman aperture 12. The plunger 9 is normally to be projected within one ofthe apertures 12, and to hold said plunger in its normal position aspring 1() is encircled about the plunger 9, one end of said springbearing against the top of the sleeve 7 and the opposite end against acollar 11, which is adjustable on the plunger 9 in order that thetension of the spring may be varied. Thus it is to be seen that thcplunger 9 acts as a lock for holding the table 6 against rotation forthe purpose to be hereinafter disclosed. In order to limit thc upwardmovement of the plunger 9, a sleeve or collar 9 is carried thereby,adapted to abut the platform, as shown in dotted lines, Fig. 1.

On the platform 5 is rotatably IOOl Arranged above each of the apertures12 is a mold 13, and each of the molds carries an ejector-plunger 14,which is so positioned as to be directly over or slightly within. auaperture 12.

Secured to the bed-plate 3a and beneath the platform 5 is a cylinder 16,provided with a piston-rod 15, and the rod 15 is adapted to pass throughan aperture 15:L in the platform 5 andcontact with and raise theejector-plunger 14 for the purpose readily understood. The cylinder 16is supplied with air, steam, or other fluid in any well-known orpreferred manner for operating the piston-rod 15. It is to be noted thatthe aperture 15L coincides with the apertures 12 of the table 6. Carriedby the bed-plate 3a are the opposed uprights or posts 18, which extend asuitable distance above the table 6. T he tops of the posts 18 areconnected by cross-beams 19 and 20, and intermediate the length of eachpost is a web or bracket 17, on which rests an edge,

of the platform 5 ,said platform being secured thereto by bolts 17. Bythis means the strain of the platform is distributed to the post.Extending upwardly from the crossbeams 19 and 20 and secured thereto isa standard 27, which has pivoted to its free end a lever 27. One end ofthe lever 27 has pivoted thereto an end of a rod 21, which passesthrough the cross-beams 19 and 20.

The lower end of the rod 21 carries a yoke 26, which is adapted to beadjusted thereon, said adjustment being attained by the nut 22, swiveledin the top plate 23 of the yoke and engaging a threaded portion 22l ofthe rod 21.

Attached to the yoke 26 is a presser-head 24, adapted to engage each ofthe molds 13 as they are successively brought thereunder. The mold andhead are similar in construction to a device described in a companionapplication, and speciiic details thereof are thought to be unnecessary,except to the fact that the action of the plunger on the material withinthe mold is Vfrom the top and on the exterior at all times. In otherwords, the compression of the material is confined within thepresser-head and not between the presserhead and walls of the mold, asis the general art. To accomplish this result, the outer surface of thepresser-head must 'lit snugly within the mold, an arrangement which isfully illustrated in the drawings.

The opposite end of the lever 27 is secured to a rod 28, working in acylinder 29, which cylinder receives its iluid in any well-known orpreferred manner, It is to be noticed that the cylinder 29 is arrangeddirectly over one of the posts 18. By this means much pressure isrelieved from the cross-beams 19 and 20 and any undue strain isobviated, as the strain of the cylinder in operating the rod is given.directly and solely to the post.

The table 6 is similar to that disclosed in a companion application, andas the parts thereof not mentioned herein are fully described thereinadditional description is thought unnecessary.

In operation suitable material is placed within the molds 13, and thetable 6 is held against rotation by the plunger 9. By means of thecylinder 2S and its associate parts the rod 21 forces the head 24 intoengagement with the mold, and upon its withdrawal therefrom the plunger9 is depressed in order to allow the table to be rotated by hand orotherwise until a second mold is in position, and so on. Vhen the moldhas at length reached the aperture 15a of the platform, the rod 15 isoperated to contact with the ej ector-plunger 14 for the purposesunderstood.
